- To in whom it may concern: v Be it known that I, IRWIN S. PAYTON, a citizen' of the .United States, residing at Cleveland, in thecounty of 'Cuyahoga and- B-State of Ohio, have invented certain new and useful Improvements in Motor-Vehicle Locks, of which thefollowing. is a specifica tion.

0. 1,230,907, was issued June 26th, 1917 to Arthur W. Lamp.

The objects of the present invention are,

like those of the said patent, to provide a device of the character mentioned, which is so constructed that thesteering .column of thevehicle can not be turned by the steering wheel when the vehicle is locked. x

Another object of the present invention is to provide a construction that is more eco- I nomical and efiicient than that described in.

the prior patent.

I With these objects in view, the invention -consists in the'novel construction, combination and arrangement of parts as hereinto after described and pointed out definitely in the appended claims, reference being had to the accompanying drawings which are made partof the specification, similar ref- Terence characters being employed to desigj nate correspondingparts. I

' anal steering -'columntogether, said device being mounted in the steering wheel. These elements are embodied in the patent above referred to, and are also common factors in other appliances of this class. The salient featuresxof-the present invention are the means for efiicientlyretaining the elements 1 n roper operatlve assemblage.

1. he steering column 1 is provided with a Qhe adB, anda threaded stud 4. The steering whee 1g2 1s ournaled on the head '3, the bore '5, m the hub 6 of the wheel, being provided for this purpose- The upper portion of the hub. bore 1s of greater diameter than that part which bearson the head 3, and is internally-threaded, as shown at 6. An annular shoulder'7 is formed in the hub at the upper term nal ofthe bearing bore.

The head 3is inserted in the hub bore 5 at the lower end, a washer 8 is slipped on "the stud 4:, and aunt 9 is threaded onto said stud and bears on the washer 8. A cap 10 is provided with an external thread 10 which fits the internal thread 6 of the wheel hub. Said cap has an annular flange 10 adapted -to seat on a led e 6 formed in the hub. A

chamber 10 is a so provided in the cap, and an -1nter1or annular shoulder l0 fis adapted to bear on the washer 8 when the said cap 1s screwed into the hub of the steering wheel. A skirt 10 extends below the shoulder, 10 into an annular channel 6 in the hub 6. The cap 10 coacting with the hub 6 confines the washer 8 between the shoulder 10 and the opposing shoulder 7, and retains the head 3 rotatable in the hub 6, the chamber 10 providing clearance for the nut 9. I

Recessesf are formed in the head 3, said recesses being adapted to receive the looking on l1ne2-2 bolt '11 when operated as hereinafter described. I

. The locking mechanism is housed in an extension 6 of the hub 6, and comprises a bushing 12 in which the operating mechathe annular shoulder 7, or flush with the journal bearing, and has a slot 12 which rovides clearance for the skirt 10?. The

olt 11 is mounted in the bushing 12, and is I operated, reciprocally by the screw 13, said screw being actuated by the key-lock 14, means bemg provided for-preventing rotation of the bolt 11 relatively to-the bushing.

' bearing on a fiat surface 12 in the bushing the slot 12 in the bushing 12. The skirt 12 prevents rotation of the bolt, and permits reciprocation of said bolt. The bolt 11 is provided With a groove 11 in the top, and

when the bolt is seated in one of the recesses 3 of the head 3, said groove registers with is provided with a notch 10, as shown in Fig. 4. When the bolt 11 is withdrawn clear of the recess3, it engages the notch 10 and thereby prevents revolution of'the cap 10.

Therefore when the steering wheel is loose on the steering column the cap cannot be removed, but when the wheel is locked to the column the cap ma be unscrewed, as the skirt 10 will clear t e bolt 11, in the groove 11. Holes 10 are provided in the face of the cap to accommodate a spanner wrench. The top of the cap 10 provides a convenient location for a name plate, and if desired,

' the holes 10 may be threaded and a plate tion of the steering column; a journal head on said column; the steering wheel hub journaled on sa1d head; a stud extending upward from said head; a washer .on said stud; a shoulder in the hub bore, on which said washer bears; a retaining nut on the stud; a cap provided with a chamber, screwthreaded in the top of the hub bore and adapted to bear on top of the washer; oneor more radial recesses in the head;-a reciproeating bolt mounted in the wheel member and adapted to register with said recesses; and lock mechanismfor actuating said bolt.

2. In a motor vehicle lock, the combination of the steerin column; a journal head on sa1d column, sa1d head provided with one or more radial recesses; the steering wheel radially from the journal bearing;

ating said bolt, mounted in said bushing and hub ournaled on sa1d head; a tubular bushmg confined 1n the wheel hub and extending a reciprocating bolt, and lock mechanism for actuadapted to register with the recesses in the journal head; a stud extending upward 7 from the journal head; a washer on said stud; a shoulder in the hub, on which said washer bears; a retaining nut on the stud; a cap provld'ed with a chamber, screwthreaded lnto the top of the hub bore; a

shoulder on said cap adapted to bear on the 1 washer, and a skirt on said cap depending.

below said washer through a slot provided in the bushing member, said skirt being pro- "vided with a notch which engages the bolt 2 when sa1d bolt is withdrawn from the recesses in the head. In testimony IRWIN PA TON.
